8. Put the System Device Cover back and tighten 9 Screw A’s.
To install the DIMM under the keyboard, do the following:
1. Remove Screw D.
2. Find the keyboard latches near the edges of the keyboard.
The latch is spring-loaded. It will retract when pressed and
revert back to its original position when released. Use a small
blade to press the latch inward. The keyboard tray should pop
up slightly over the latch. If the keyboard tray does not pop up, try to
gently lift it up slightly above the latch. Repeat this step for the
other keyboard latches.
